What would a good political party look like?

[Lougle]

Reform are Right of Right and frankly scary
Conservatives are trying to be the slightly more palatable Reform
Labour are in a pickle and can't even decide where they are
Lib Dems say anything they can go get into parliament, then go back on their word
Green have crazy policies

What would a good party look like and could it be created by May? When does a party need to exist before people can vote for it in a GE?

Well a lot of people obviously don't agree with you about the Green Party!

How could one possibly just be straightforwardly 'good'? They exist to represent different points of view so people's opinions will differ. It's also the case that it's easier to be straightforwardly values-based when you've never been in government - the Greens and Plaid have no baggage of mistakes in government (or any kind of track record either) so they can be more of a blank slate to project onto. Same with Reform to some extent. Once parties have been governing a while, there will always be people they've pissed off.

Which specific green party policies do you consider crazy.
Also, the Lib Dem incident you describe happened more that a decade ago and none of the people involved are around. I highly doubt that lying to get into the government is an official party line. When are we going to stop bringing this up?
There will never be a party which please everyone or does everything perfectly - it's simply not possible. A good political party for me is the one which relies on evidence for decision-making and I don't think (m)any do. I also recognise that the governance is a complicated process with many cogs we may not actually see or understand and policy changes are less simple than just saying "why don't we do X" because every decision needs to be impact assessed. Calculating probabilities of every outcome is likely to be a statistical nightmare.

I'd love to see a party where ministers are allocated areas according to their expertise as the first step. I can't comprehend someone floating from being a health minister to being a chancellor to being a foreign secretary. These are three completely different areas and it would be infinitely more helpful if a health minister had some background of NHS work rather than spend the first two years trying to understand how the system works before being swiftly moved on to become a transport minister.
